Application filed September 20, 1904. Serial No. 225,183.

To all 7.077.077@ it r11/ay concern:

Be it known that I, HENRY L. CARPENTER, of Minneapolis, Hennepin county, Minnesota, have invented new and useful Improvements in Fire-Extinguishers, ot' which the following is a specification.

My invention relates to tire-extinguishers, and particularly to those oi' the hand type.

rIhe object of the invention is to provide means for insuring the successful discharge under pressure or' the contents of a bottle lled with a lire-extinguishing liquid.

The invention consists generally in providing a locking means in connection with the inner cork or plugl of a bottle or receptacle containing a charged lire-extinguishing liquid to prevent said cork or plug from being accidentally blown out of the bottle when the pressure is released by the removal of the outer cork.

In the accompanying drawings, forming part ot' this specilication, Figure l is a vertical section of a lire-extinguisher with my invention applied thereto. Fig. 2 is a sectional view of the top of the bottle, showing a modiiied means for connecting the tube to the inner cork or plug. Fig. 3 is adetail sectional view of the neck ot' the bottle, showing a modified form of locking device. Fig. 4 is a detailof the locking device shown in Fig. 3. Fig. 5 is a modified form of locking device, and Figs. 6 and 7 illustrate further modilications.

In the drawings, 2 represents a bottle of suitable size and shape adapted to be held in the hand and having a neck 3, provided with an annular groove or recess 4 for the purpose ot' weakening the bottle-neck at that point. The outer cnd of the neck is hermetically sealed by cork or plugr5, secured against any accidental discharge from the bottle by means of wires 6. In placev of the cork or plug a plastic'material that will harden or set after being placed in the neck may be used. rlhe inner end of the cork 5 preferably terrni= nates opposite the groove 4. Below the cork 5 and the groove 4 is a second or inner cork 7, having a hole 8 extending therethrough and provided with a tube 9, of any suitable material, that extends into the bottle and has its open end near the bottom of the bottle.

The outer end of the bottle-neck is broken or knocked off by striking it against the corner of a table, chair, or other object preparatory to using' the extinguisher, and to prevent the pressure of the charged liquid from forcing the inner cork out of the bottle when the outer one is removed VI provide a locking device interposed between said inner cork and the outer one and arranged to eifectually lock said inner cork against any possible dislodgnlent by the pressure ot' the gas in the bottle. This locking device may consist of a spiderlike device 9, of metal or any other suitable material, having a hole 10, coinciding with the hole in the cork, and arms 11, that are adapted to enter an annular recess 12 in the neck of the bottle and prevent any possible outward movement ot' the cork, the arms being preferably sprung into place, so that the locking device will assume a concave form, as shown in Figs. 1 and 2. A tube 13 is preferably provided on the under side of the locking device, fitting snugly into the hole in the cork and abutting the upper end of the tube 9.

In Fig. 6 I have shown a modification in the form of the locking device which consists o't' a disk 14, of any suitable material, preferably thin sheet metal, capable of being used in the Jform shown in Figs. 1 and 2. It preferred, some plastic material may be employed in place of the metallic disk, which, after becoming hardened, will securely lock the cork in the neck of the bottle.

In Fig. 5 I have shown still another modiiication in the locking device, which consists in providing a wire coil 15, having its ends inserted into the top ot' the cork and the coils following the circumference of the same and adapted t0 spring outwardly into the recess and hold the cork in place.

In-Figs. 3 and 4 still another modilication is shown, which consists in providing a recess 16 a little lower down in the neck of the bottle and `arranging a wire 17 over the top of the cork having depending hooked ends 18, adapted to enter the recess and hold the cork in place.

Various modifications in the manner ot' securing the inner closing' means in the neck may be employed, and hence I do not wish .to be confined to the devices shown and described herein.

I claim as my invention-- 1. As a new article of manufacture, a receptacle having a neck provided with a weakened area, Stoppers closingI said neck above and below said area, a locking device engaging said neck and preventing the accidental discharge of said inner stopper, and a tube communicating with the interior ot' said receptacle and with the space between said Stoppers.

2. As a new article of manufacture, a receptacle having a neck provided with a weakened area and having an annular groove or recess below said area, Stoppers closing said neck upon each side o't' said area, a locking device extending across the inner stopper and entering said recess to prevent the accidental discharge of said inner stopper, and a tube communicating with said receptacle and with the space between said Stoppers.

3. As a new article of manufacture, a bottle adapted to contain a liquid under pressure and provided with a neck having a weakened area and a recess below said area, Stoppers closing said neck above and below said area, the inner stopper having a hole extending therethrough, a disk having a hole coinciding with the hole in said inner stopper, and edges adapted to enter said recess, and a tube fitting the hole in said inner stopper and extending into said bottle, substantially as described.

4. As a new article of manufacture, a bottle having a neck provided with a weakened area, Stoppers closing said neck upon each side oi' said area, the inner stopper having a hole extending therethrough, atube extending into the bottle and communicating with said hole, and a locking device interposed between said inner and outer stopper and engaging' the neck of the bottle and preventing the accidental discharge of said inner stopper, substantially as described.

5. As a new article of manufacture, a receptacle having a neck provided with a weakened area, means Jor closing said neck between said area and the receptacle, said closing means having an orifice extending therethrough, a tube communicating with saidl
